Hand, foot, and mouth disease (HFMD) is a common viral infection caused by a group of enteroviruses, most commonly coxsackievirus A16. It is characterised by fever, mouth sores, and a skin rash. While HFMD usually affects children under five years old, anyone can contract the illness. Although HFMD is typically mild and self-limiting, severe complications can arise in rare cases, affecting the nervous system and potentially leading to cardiopulmonary failure. Currently, there is no vaccine available for HFMD in the United States. However, China developed an EV-A71 vaccine in 2016, and efforts are underway to create a vaccine in other countries.

There is currently no vaccine for hand, foot, and mouth disease (HFMD) in the US
Hand, foot, and mouth disease (HFMD) is a common infection caused by a group of enteroviruses, with human Enterovirus A71 (EV-A71) and Coxsackievirus 16 (CV-A16) being the primary culprits. It is highly contagious and usually causes fever, mouth sores, and skin rash. While the illness is usually not serious, and most people recover within 7 to 10 days without any specific treatment, HFMD can occasionally lead to severe complications affecting the nervous system and, in rare cases, even result in death.
Currently, there is no vaccine available to protect against the viruses that cause HFMD in the United States. While China developed an EV-A71 vaccine in 2016, which has proven effective in reducing infection rates, it is not widely available in other countries due to regional licensing and production constraints. The absence of a vaccine in the US underscores the need for preventive measures, such as frequent hand washing, disinfecting surfaces, and avoiding close contact with infected individuals.
The development and implementation of an effective HFMD vaccine are crucial to reducing the incidence and severity of the disease. An ideal vaccine should be affordable, safe, mass-producible, easy to administer, and acceptable to parents. Governments, health organizations, and the global community must collaborate to overcome barriers and ensure broader immunization coverage.
In the absence of a vaccine, the focus is on managing symptoms and preventing dehydration. Over-the-counter medications can help relieve fever and pain caused by mouth sores, but aspirin should be avoided, especially in children. Maintaining good hygiene practices and adhering to preventive measures remain vital until a vaccine is accessible to protect against this contagious disease.

An EV-A71 vaccine was developed in China in 2016
Hand, foot, and mouth disease (HFMD) is a common illness that usually causes fever, painful mouth sores, and a skin rash on the hands and feet. It is highly contagious and common in children under 5 years old, but anyone can get it. While most people recover within 7 to 10 days, HFMD can occasionally cause severe and even fatal complications, especially in children under 3 years old.
HFMD is caused by multiple enteroviruses, including Coxsackievirus A16 (CA16), Coxsackievirus A6 (CA6), and Enterovirus A71 (EV71). EV71 is a major causative agent of HFMD and is associated with severe and fatal cases, especially in children. In China between 2009 and 2018, nearly 70% of severe and over 90% of fatal HFMD cases were caused by EV71.
To combat the burden of EV71-associated HFMD, China introduced an EV71 vaccination program in 2016. Three inactivated EV71 vaccines, developed by Chinese manufacturers, were licensed in China during 2015-2016. These vaccines underwent Phase III clinical trials, demonstrating good immunogenicity and safety profiles. The trials showed that the efficacy of the EV71 vaccines against EV71-associated HFMD was higher than 90%.
The impact of the EV71 vaccination program in China has been positive. A longitudinal surveillance study in Guangdong, China, from 2012 to 2019, observed a relative reduction of 41.4% in EV71-associated HFMD cases during the post-vaccination period of 2017-2019. This reduction corresponded to 26,226 averted cases. The study also found that the reduction in EV71-associated HFMD cases increased with higher EV71 vaccine coverage.
While the EV71 vaccine has proven effective, it is important to note that it may not protect against HFMD caused by other viruses such as CA16 or CA6. Additionally, the vaccination rate for EV71 remains low across China, with coverage rates for the two required doses varying between provinces and cities.

The EV-A71 vaccine was proven effective in a 12-month analysis
Hand, foot, and mouth disease (HFMD) is a common illness in children under five years old, but anyone can get it. It is usually not serious, but it is highly contagious. Currently, there is no US FDA-approved vaccine against EV-A71, which is one of the major causative agents of HFMD outbreaks.
However, there is promising research on the development of EV-A71 vaccines, particularly in China. The EV-A71 vaccine was proven effective in a 12-month analysis as part of a randomized, double-blind, placebo-controlled trial. This trial included 10,007 healthy infants and young children (aged 6 to 35 months) who were randomly assigned to receive either the EV-A71 vaccine or a placebo, with a 28-day interval between doses. The surveillance period was 12 months, during which the occurrence of EV-A71-associated HFMD was monitored.
The results of the trial showed that the EV-A71 vaccine was highly effective in preventing the disease. During the 12-month surveillance period, EV-A71-associated HFMD was identified in only 0.3% of vaccine recipients, compared to 2.1% of placebo recipients. This translates to a vaccine efficacy of 94.8% against EV-A71-associated HFMD or herpangina.
In addition to this trial, there have been other studies supporting the effectiveness of the EV-A71 vaccine. One study found that the vaccine efficacy against EV-A71-induced HFMD was 90% in the first year and reached 100% in the second year. Another study in Chengdu, China, reported a two-dose schedule of the EV-A71 vaccine was 63.4% effective against symptomatic HFMD requiring hospitalization over a five-year period.
While these findings are encouraging, it is important to note that the EV-A71 vaccine is not yet approved for widespread use. The safety and immunogenicity of the vaccine are still being evaluated in clinical trials. However, the research suggests that the development of an effective vaccine against HFMD is a promising area of study, and it may offer the best option for disease control in the future.

HFMD is a contagious viral illness that predominantly affects infants and young children
Hand, foot, and mouth disease (HFMD) is a contagious viral illness that predominantly affects infants and young children. It is caused by a variety of viruses, with human Enterovirus A71 (EV-A71) and Coxsackievirus A16 (CV-A16) being the primary causes. HFMD is common in children under five years old, but anyone can get it. The illness is usually not serious, and most people recover within 7 to 10 days without any specific treatment. However, it is highly contagious and can spread quickly in schools and daycare centers.
The symptoms of HFMD typically include fever, mouth sores, and a skin rash on the palms, soles, and sometimes the buttocks and groin. The rash may appear as flat discolored spots or bumps that can blister. Other symptoms can include nausea, vomiting, fatigue, loss of appetite, and irritability in infants and toddlers. While rare, more severe complications can arise, affecting the nervous system and, in some cases, leading to cardiopulmonary failure. These severe cases can result in lasting cognitive and motor disorders or even death, particularly in infections caused by EV-A71.
Currently, there is no vaccine available to protect against HFMD in the United States. However, China developed an EV-A71 vaccine in 2016, and it has been available in the country since December 2015. This vaccine has significantly reduced the infection rate in vaccinated individuals. There is a pressing need to develop and deploy large-scale HFMD vaccination programs, especially in endemic countries, to reduce the incidence and severity of the disease.
To prevent the spread of HFMD, it is essential to practice good hygiene, including frequent hand washing and disinfecting surfaces. Infected individuals should also avoid close contact with others. While there is no specific treatment for HFMD, over-the-counter medications can help relieve fever and pain caused by mouth sores. It is important to stay hydrated and seek medical attention if symptoms persist or worsen.

HFMD is usually not serious and most people recover within 7-10 days
Hand, foot, and mouth disease (HFMD) is usually a mild illness that does not require specific treatment. Most people recover within 7 to 10 days without any medical intervention. The disease is characterised by fever, mouth sores, and a skin rash that typically appears on the palms, soles, and sometimes the buttocks and groin. It is caused by a variety of viruses, with human enterovirus A71 (EV-A71) and Coxsackievirus A16 (CV-A16) being the primary culprits. While HFMD is common in children under five years old, anyone can get it.
The illness is highly contagious and can spread through close personal contact, coughing, or contact with the faeces of an infected person. To prevent the spread of HFMD, it is important to practice good hygiene, including frequent hand washing, disinfecting surfaces, and avoiding close contact with others while symptomatic.
While HFMD is typically mild and self-limiting, more severe complications can arise in rare cases, affecting the nervous system and, in very rare instances, leading to cardiopulmonary failure. These severe cases can result in lasting cognitive and motor disorders or even death, particularly in infections caused by EV-A71. Therefore, it is important to monitor symptoms and seek medical attention if they persist or worsen.
Currently, there is no vaccine available to prevent HFMD in most countries. However, China developed an EV-A71 vaccine in 2016, and its use has significantly reduced the infection rate in vaccinated individuals. Efforts are underway to develop and implement effective HFMD vaccines on a larger scale, as this would substantially reduce the incidence and severity of the disease.
In summary, while HFMD is usually a mild and self-limiting illness, it can cause significant discomfort and has the potential to lead to rare but severe complications. The development and distribution of vaccines, along with proper hygiene practices, are crucial in mitigating the impact of HFMD and preventing its spread. Most individuals recover within 7 to 10 days without treatment, but it is important to remain vigilant and seek medical advice if symptoms persist or worsen.
